SOUTH Insight V3 Visual Positioning IMU RTK GNSS Receiver

Visual RTK GNSS Surveying for Demanding Fieldwork

The SOUTH Insight V3 is an advanced RTK GNSS receiver developed for surveyors, construction professionals, engineers and GIS teams that need accurate positioning with a more visual and flexible field workflow. It combines a 1698-channel GNSS board, dual cameras, fifth-generation IMU tilt compensation and multiple correction links in one rugged receiver.

It can be used for topographic surveying, construction stakeout, road and infrastructure work, earthworks, boundary and cadastral measurement, utility mapping, GIS asset collection and ground control for drone surveys. The camera functions also provide practical options for points that cannot be occupied safely or directly with the survey pole.

Dual-Camera AR Stakeout

The Insight V3 uses front and downward-facing cameras to support augmented-reality stakeout. In compatible SOUTH field software, navigation information is placed over the live camera view, helping the operator see which direction to walk and where the design point lies in relation to the pole.

This is useful when setting out foundations, building grids, kerbs, utilities, road alignments, boundaries and other design features. Points, lines and curves can be approached using visual guidance, reducing the amount of time spent interpreting conventional compass arrows and distance values.

The downward-facing camera provides close-range guidance as the operator reaches the target. This gives the user a clearer view during the final part of the stakeout process and can make repetitive site layout easier to follow.

Visual Positioning for Inaccessible Points

Visual positioning allows the operator to calculate coordinates from photographs or video instead of physically placing the pole tip on every point. In suitable conditions, objects more than 10 metres away can be measured remotely. Actual working distance and accuracy depend on image quality, geometry, lighting, movement and the surrounding environment.

This function is valuable when measuring building façades, roof edges, trench features, points behind barriers, busy road areas, water edges or other locations that are difficult or unsafe to access. A group of images or a video can also be used to collect multiple points more efficiently than measuring each feature individually.

The recorded image information remains useful after leaving the site. Surveyors can return to the visual data when additional points or context are required, reducing the likelihood of a second visit for an overlooked feature.

Fifth-Generation IMU Tilt Compensation

The integrated IMU compensates for a pole tilt of up to 60°. The operator can place the pole tip on the required point and record the position without carefully centring the bubble for every measurement.

This speeds up routine point collection and helps around building corners, beneath vegetation, beside walls, near machinery and on sloping or uneven ground. The IMU does not rely on a magnetic compass, so nearby metal structures and other sources of magnetic interference have less effect on the tilt workflow.

Fast IMU availability also supports a smoother transition between conventional measurement, visual positioning and AR stakeout. As with every tilt-compensated system, good pole-height settings and correct field procedures remain important for dependable results.

1698-Channel Multi-Constellation GNSS Engine

The SOUTH S805 GNSS platform provides 1698 channels for tracking signals from GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS and other supported services. Multi-frequency tracking gives the receiver access to a broad selection of satellite observations and helps it maintain positioning availability across varied working environments.

More available signals can support faster fixed solutions and more stable field performance near trees, buildings and other partial obstructions. Dense overhead cover and reflective surfaces can still affect every satellite receiver, so actual results depend on satellite geometry, correction quality, atmospheric conditions and the local surroundings.

Dual Positioning Algorithms

The Insight V3 includes two GNSS positioning algorithms. During unusual ionospheric conditions, network RTK users may experience a solution that appears fixed but contains an increased position error. The receiver’s enhanced positioning mode provides an alternative processing engine designed to help recognise and address this type of problem.

This feature gives survey crews an additional option when normal VRS or CORS performance becomes less predictable. It does not replace normal quality checks, control-point verification or good surveying practice, but it can improve confidence when working during difficult ionospheric periods.

4G NTRIP and Farlink 2.0 UHF

The built-in mobile modem allows the receiver to obtain RTK corrections from compatible NTRIP, CORS and VRS services. This makes it suitable for use as a network rover without setting up a local base station, provided that mobile coverage and a suitable correction subscription are available.

An integrated 410–470 MHz radio supports work with a compatible GNSS base. The Farlink 2.0 protocol is designed to carry a larger correction data stream with stable transmission over long distances. SOUTH states an operating range of up to 10–12 km in ideal conditions, although actual radio range depends on terrain, antennas, output power, interference, regulations and physical obstructions.

A lock-base function allows the rover to remain connected to the selected base when several transmitters are operating on the same frequency. The radio also supports several commonly used communication protocols for greater compatibility with existing field equipment.

Ground Data for 3D Modelling and Drone Surveys

The camera system can collect image data for supported 3D modelling workflows. Ground photographs captured with the Insight V3 can supplement aerial data where a drone cannot clearly see vertical surfaces, covered areas or features beneath overhangs.

This can help drone pilots, surveyors and engineering teams fill gaps in photogrammetric models and document excavation areas, infrastructure or urban sites from ground level. Coordinates, areas and volumes can then be handled in compatible SOUTH or third-party processing workflows, depending on the chosen software configuration.

Rugged Receiver for Everyday Site Conditions

The Insight V3 has an IP68-rated housing designed to protect the electronics against dust and temporary water immersion. It is also specified to withstand a natural 2 metre pole drop onto concrete, making it suitable for regular construction and surveying environments.

An internal 6800 mAh rechargeable battery provides up to 25 hours of operation in rover mode under stated test conditions. Battery duration in real fieldwork varies with radio use, mobile communication, camera operation, temperature and receiver settings.

The integrated colour display provides access to status information and basic configuration options. A browser-based Web UI can be opened through Wi-Fi or USB for receiver monitoring, satellite selection, base and rover setup, radio configuration, data recording, file transfer and firmware management.

Flexible Data and Integration Options

The receiver supports commonly used survey and GNSS data formats, including RTCM corrections, NMEA navigation output and RINEX static observation files. Internal storage and USB connectivity simplify the transfer of recorded field data to an office computer.

Open data interfaces and development options also allow the Insight V3 to be integrated into specialised surveying, GIS, machine or monitoring workflows where compatible software and technical resources are available.

Who Uses the SOUTH Insight V3?

Land surveyors can use the receiver for control, detail measurement, boundaries and setting out. Construction teams can position foundations, grids, utilities, kerbs and other site elements. Civil engineers can document roads, structures, earthworks and public infrastructure, while GIS teams can collect accurate coordinates and visual context for assets in the field.

Drone and photogrammetry operators can use it to establish ground control points, measure independent checkpoints and collect ground-level images that complement aerial mapping. The visual workflow is also helpful for less specialised construction personnel because it makes navigation to a stakeout point easier to understand.

Receiver Configuration and Support

This product page covers the SOUTH Insight V3 receiver rather than a complete rover set. A compatible data collector, field software, survey pole, controller bracket and RTK correction source may be required to create a complete working system.

Global GPS Systems can help select a suitable controller, software package, correction service, radio configuration and accessories for the intended country and application. This is especially important because mobile networks, UHF frequencies, coordinate systems and local surveying workflows differ between regions.
